  The drive device has a plurality of motors composed of, for example, a vibration wave motor and a VCM, and drives the focus lens in the optical axis direction. Further, the anti-vibration lens is driven in a direction different from the optical axis direction. The lens CPU 7 has a lens CPU 7 that controls the entire photographing lens 3 and cooperates with the camera body 2.

  The camera body 2 includes a main mirror 10. The main mirror 10 retreats so that the light beam from the photographic lens 3 is reflected and guided to the finder optical system 8 and the light beam from the photographic lens 3 is incident on the image sensor 9 composed of a CCD or a CMOS. Swings between the retracted position.

  In the camera body 2, a partial region of the main mirror 10 is a semi-transmissive region, and a sub-mirror 12 that reflects the light beam transmitted through the semi-transmissive region to the focus detection sensor 11 is disposed. The sub mirror 12 swings in conjunction with the main mirror 10, and when the main mirror 10 takes the retracted position, the sub mirror 12 also retracts from the light flux. The focus detection sensor 11 detects the focus state of the incident light beam by the phase difference method.

  The light beam reflected by the main mirror 10 at the reflection position is guided to the finder optical system 8 through the focusing screen 13 and the pentaprism 14. The finder optical system 8 includes a plurality of lenses, and the user can confirm the object field by the finder optical system 8.

  A part of the light beam passing through the pentaprism 14 is guided to the photometric sensor 15. The photometric sensor 15 measures the luminance distribution of the object scene by measuring the light beam incident on the photographing lens 3 for each of a plurality of regions. A GPS (Global Positioning System) module 16 is provided above the pentaprism 14.

  Further, the camera body 2 includes a microphone 17 that records the sound of the object scene at a position near the mount portion of the photographing lens 3 so as not to interfere with the photographing lens 3. The camera body 2 includes a speaker 18 that emits a beep sound in the vicinity of the finder optical system 8.

  When the main mirror 10 is in the retracted position, the light beam from the photographing lens 3 enters the image sensor 9 through the low-pass filter 19. An imaging board 20 is provided behind the imaging device 9, and a rear monitor 21 is provided behind the imaging board 20 so as to face the outside.

  FIG. 2 is a block diagram of the camera system 1 according to the present embodiment. Elements that are the same as those in FIG. 1 are given the same reference numerals, and redundant descriptions are omitted.

  The main body CPU 27 controls the entire camera system 1 in cooperation with the lens CPU 7. The imaging board 20 connected to the main body CPU 27 includes a drive unit 23 that drives the imaging device 9, an A / D conversion unit 24 that converts the output of the imaging device 9 into a digital signal, an image processing unit 25 that includes an ASIC, and imaging. A contrast AF circuit 26 that extracts a high-frequency component of the signal from the element 9 is provided.

  The image processing unit 25 performs image processing such as white balance adjustment, sharpness adjustment, gamma correction, and gradation adjustment on the image signal converted into the digital signal and generates an image file by performing image compression such as JPEG. To do. The generated image file is stored in the secondary recording medium 34. The secondary recording medium 34 may be a recording medium such as a flash memory that can be attached to and detached from the camera body 2, or may be a recording medium such as an SSD (Solid State Drive) built in the camera body 2. good.

  The image signal subjected to the image processing is displayed on the rear monitor 21 under the control of the rear monitor control unit 28. If the image signal taken immediately after shooting is displayed for a predetermined time, the image corresponding to the image file recorded on the secondary recording medium 34 can be viewed by the user.

  Further, if the subject image photoelectrically converted by the image sensor 9 is continuously displayed on the rear monitor 21 without being stored in the secondary recording medium 34, live view display can be performed. When the live view is displayed, the image of the object scene is displayed on the rear monitor 21.

  Furthermore, if the subject image that is continuously photoelectrically converted by the image sensor 9 is continuously recorded on the secondary recording medium 34, moving image shooting can be performed. In this case, the moving image file to be recorded is MPEG, H.264 by the image processing unit 25. H.264 is a moving image compression process. In addition, when shooting moving images, the microphone 17 can also record sound. The frame rate of a moving image generated by moving image shooting is set to, for example, 30 fps from a plurality of frame rates.

  The contrast AF circuit 26 extracts a high-frequency component of the imaging signal from the imaging device 9 to generate an AF evaluation value signal, and detects a focus lens position where the AF evaluation value signal is maximized. The detected AF evaluation value signal is referred to by the main body CPU 27.

  The lens CPU 7 has an optical camera shake correction function that cancels the camera shake detected by the angular velocity sensor 6 by driving the image stabilizing lens in the photographing lens 3 in a direction different from the optical axis direction. On the other hand, the camera body 2 also has an electronic camera shake correction function that calculates a motion vector between a plurality of images output from the image processing unit 25 and cancels the motion vector between images by changing the image reading position. Prepare. Optical camera shake correction is suitable for still image shooting, and electronic camera shake correction is suitable for moving image shooting.

  The photometric sensor 15 measures the luminance distribution of the object scene by measuring the luminous flux incident on the photographing lens 3 for each of a plurality of regions. The measurement result is referred to by the main body CPU 27. The main body CPU 27 calculates an exposure value according to the selected photometry mode. The metering mode can be selected from a split metering mode that balances a bright part and a dark part, a center-weighted metering mode in which the center of the screen is properly exposed, and a spot metering mode in which a narrow area of the selected focus point is appropriately exposed.

  The calendar unit 54 includes a crystal oscillator, a timekeeping integrated circuit, and the like, and generates calendar information such as year / month / day / hour / minute / second. The main body CPU 27 can acquire information on the date and time from the calendar unit 54.

  The GPS module 16 receives a GPS signal from a GPS satellite and calculates latitude, longitude, and altitude information where the camera body 2 exists. The main body CPU 27 acquires position information regarding the position of the camera main body 2 from the GPS module 16. Since the GPS signal includes highly accurate time information, the calendar unit 54 can be calibrated from the GPS signal received by the GPS module 16.

  The flash ROM 29 includes an EEPROM (registered trademark), and stores various adjustment values and setting values in addition to a program for operating the camera system 1. Specifically, setting values such as AF adjustment data, AE adjustment data, manufacturing date / time data, and setting switch setting history are stored. The flash ROM 29 also stores a use history of the menu setting screen and the user guide screen. Further, the flash ROM 29 also stores a deletion history file and a failure avoidance setting file which will be described later.

  Among the setting values stored in the flash ROM, setting values that are set or changed by the user are prepared as menu items on a setting screen displayed on the rear monitor 21. Further, as will be described later, the flash ROM 29 is also responsible for accumulating deletion history including shooting conditions for deleted images and storing failure avoidance settings.

  The RAM 30 is a high-speed RAM such as a DRAM that can be accessed at high speed by the main body CPU 27, and a program stored in the flash ROM 29 is expanded. Further, adjustment values and setting values that are frequently referred to may be copied from the flash ROM 29 to the RAM 30 so that the main body CPU 27 can be accessed at high speed.

  The failure avoidance setting calculation module 55 calculates and generates a failure avoidance setting, which will be described later, from the deletion history stored in the flash ROM 29. The failure avoidance setting calculation module 55 writes and stores the calculated failure avoidance setting in the flash ROM 29. The failure avoidance setting will be described later.

  The rear monitor control unit 28 displays a menu setting screen and a user guide screen read from the flash ROM 29 on the rear monitor 21 in addition to the captured image subjected to image processing. The rear monitor 21 has a touch panel sensor laminated on the surface. The user can operate the touch panel sensor while visually recognizing menu items and the like displayed on the rear monitor 21. The instruction input from the touch panel sensor is referred to the main body CPU 27.

  The direction sensor 33 includes a geomagnetic sensor and detects which direction the camera system 1 is facing. The IP communication unit 31 includes a network connection unit based on the Internet protocol and a program for acquiring information from the network. As a result, the IP communication unit 31 acquires event information including the date, place, and the like where the event is held via the network.

  The release switch 32 is pressed when the user instructs the camera system 1 to take a shooting timing. When the user half-presses the release switch 32, the main body CPU 27 executes photographing preparation operations such as autofocus and photometry. When the user further presses the release switch 32, the main body CPU 27 starts still image shooting or moving image shooting.

  FIG. 3 is a rear view of the camera body 2. Elements that are the same as those in the other drawings are given the same reference numerals, and redundant descriptions are omitted.

  A rear end of the finder optical system 8 and a rear monitor 21 are arranged in the center of the rear surface of the camera body 2. On the side of the rear monitor 21, a rear dial 35, a cross button 36, an enter button 37, a playback mode button 38, a delete button 39, a confirmation button 40, and the like are arranged.

  The camera body 2 operates in the playback mode when the playback mode button 38 is pressed. In the reproduction mode, the captured image data stored in the secondary recording medium 34 is displayed on the rear monitor 21. By rotating the rear dial 35 in this state, the captured images displayed on the rear monitor 21 are sequentially switched. Thus, the back dial 35 forms a selection unit for selecting an image.

  If the delete button 39 is pressed when an image on the rear monitor 21 is displayed in the playback mode, the displayed image can be deleted from the secondary recording medium 34. However, when the image deletion is completed in one operation, the photographed image data may be deleted due to an erroneous operation. Therefore, when the confirmation button 40 is pressed after the delete button 39, the deletion is executed.

  The cross button 36 has switches that are individually turned on / off at four locations, top, bottom, left, and right. Thereby, for example, the cross button 36 can be used when selecting an image or option two-dimensionally arranged on the rear monitor 21. In addition, individual functions may be temporarily assigned to the four switches included in the cross button 36.

  The decision button 37 is pressed when inputting an instruction to decide an option selected by the cross button 36. As a result, as in the case of the confirmation button 40, it is possible to prevent any operation from being confirmed by one operation.

  FIG. 4 is a diagram illustrating one display image displayed on the rear monitor 21 when the camera body 2 is in the playback mode. In the illustrated example, a plurality of reduced images 49 corresponding to a plurality of photographed image data are displayed on the rear monitor 21. The plurality of reduced images 49 are arranged in the order of imaging as indicated by, for example, a one-dot chain line in the figure.

  The user operates the rear dial 35 with respect to the plurality of reduced images 49 displayed on the rear monitor 21 to move the selection frame 43 indicated by a dotted line in the drawing in the order of shooting indicated by a one-dot chain line in the drawing. Thereby, photographed image data corresponding to one reduced image 49 is specified. By pressing the delete button 39 in this state, deletion of the captured image data corresponding to the reduced image 49 is instructed.

  In the rear monitor 21, a selection frame 43 whose display form has changed as shown by a solid line in the drawing is added to each of the reduced images 49 of the image data A to E instructed to be deleted by the user as described above. The Furthermore, when the user presses the confirmation button 40 after specifying all the captured image data A to F to be deleted, the captured image data is deleted. As described above, the user can collectively delete the captured image data A to F corresponding to the selected reduced image 49.

  In the above example, a plurality of reduced images 49 are displayed on the rear monitor 21 and a plurality of images to be deleted are designated. However, one image may be displayed on the entire rear monitor 21 so that an image to be deleted can be identified while checking details. In this case, for example, the delete button 39 and the confirmation button 40 are pressed for each image to delete the photographed image data one by one.

  FIG. 5 is a diagram showing the structure of the image file 50 generated by the camera system 1. The image file 50 stores tag data 51, thumbnail image data 52, and main image data 53.

  The main image data 53 corresponds to captured image data captured by the camera system 1. The thumbnail image data 52 has a lower resolution, gradation, etc., and a smaller data size than the main image data 53. Therefore, it can be easily handled when displaying an image list or the like.

  The tag data 51 stores specifications of the camera system 1, shooting conditions, and the like. When the camera system 1 is instructed to save an image in the JPEG (Joint Photographic Experts Group) format, the tag data 51 and the thumbnail image data 52 are added to the main image data 53 and saved as an EXIF file.

  In the tag data 51, information such as the manufacturer of the camera system 1 that captured the main image data 53, specifications, firmware version number, open F value, and the like are recorded. In the EXIF file, shooting information such as exposure time, F value, ISO value, focal length, shooting date and time when the image is shot is recorded. Further, the EXIF file also records additional information related to the date / time, orientation, orientation, position, event, etc. detected by the calendar unit 54, the orientation sensor 33, the GPS module 16, the IP communication unit 31 and the like of the camera system 1.

  Various information recorded in the tag data 51 is not used as shooting setting information such as exposure time and ISO value set in the camera system 1 and shooting setting values when shooting still images or moving images. It can be roughly divided into shooting environment information indicating the shooting date and time, direction, position, and the like of the camera system 1.

  Therefore, from the image file 50 recorded in the EXIF format on the secondary recording medium 34, in addition to the main image data 53 itself included in the image file 50, shooting environment information and shooting when the main image data 53 is shot. Setting information can be read. Therefore, when the image file 50 is designated as a deletion target, the main body CPU 27 can extract shooting environment information and shooting setting information included in the image file.

  FIG. 6 is a flowchart showing a control procedure of the main body CPU 27 related to deletion of image data. When deletion of the captured image is instructed by the user's operation using the cross button 36, the determination button 37, or the like, the main body CPU 27 starts the control procedure shown in FIG.

  First, the main body CPU 27 reads, from the tag data 51 of the image file 50 of the photographed image designated to be deleted, the deleted image data including the photographing setting information and the photographing environment information when the photographed image is photographed (step S101). . Next, the main body CPU 27 sequentially adds and writes the read deletion image data to the deletion history file formed in the flash ROM 29 (step S102).

  The shooting setting information included in the deleted image data may include a calculated Ev value calculated by the camera system 1 as an appropriate setting value for the deleted image and an exposure correction amount set by the user in shooting. Moreover, the color temperature calculated as an appropriate setting value by the camera system 1 and the correction value set by the user for the color temperature at the time of shooting may be included.

  The shooting environment information of the deleted image data may include information on whether or not a subject is included in addition to the shooting date and time, shooting location, shooting direction, and weather at the time of shooting. Further, the shooting environment information may include event information acquired through the IP communication unit 31 at the time of shooting. In other words, the main body CPU 27 preferably records information to be acquired as shooting environment information in the image file 50 as additional information of the tag data 51.

  Next, the main body CPU 27 causes the failure avoidance setting calculation module 55 to calculate a failure avoidance setting (step S103). The failure avoidance setting is a shooting setting suitable for the shooting environment that is calculated to avoid the shooting setting that is considered to be the reason why the user deleted the image data in the shooting environment that the deleted image data has as shooting environment information. . The procedure for calculating the failure avoidance setting will be described later with reference to other drawings.

  Subsequently, the main body CPU 27 reads the shooting environment information of the deleted image data for which the failure avoidance setting has been calculated, and checks whether or not the failure avoidance setting having the same shooting environment information is recorded in the failure avoidance setting file (step). S104). Here, the failure avoidance setting file means a file that is recorded in the flash ROM 29 and defines a plurality of failure avoidance settings.

  FIG. 7 is a schematic diagram illustrating the data structure of the failure avoidance setting file. The failure avoidance setting file defines failure avoidance settings related to shooting setting information in a state classified according to shooting environment information.

  As described above, the shooting environment information has many items such as shooting date and time, shooting location, shooting direction, weather information, person, scene mode, and event information. Therefore, in the failure avoidance setting file, each failure avoidance setting is defined in a plurality of shooting environment information, that is, a shooting environment table that forms a matrix according to time and season in the illustrated example.

  As described above, the failure avoidance setting calculation module 55 classifies and stores the calculated failure avoidance settings according to the shooting environment information. Note that FIG. 7 is merely a schematic diagram, and the failure avoidance setting may be classified by more types of shooting environment information. In that case, the dimension of the table defining the failure avoidance setting becomes high.

  Referring to FIG. 6 again, if the failure avoidance setting having common shooting environment information has already been defined in the failure avoidance setting file in step S104 (step S104: NO), the failure avoidance setting calculation module 55 has already completed. The specified failure avoidance setting is overwritten with the calculated new failure avoidance setting and stored (step S105).

  On the other hand, when the shooting environment information corresponding to the calculated failure avoidance setting is not defined in the failure avoidance setting file (step S104: YES), the failure avoidance setting calculation module 55 leaves the failure avoidance setting already defined. The newly calculated failure avoidance setting is newly defined in the failure avoidance setting file (step S107). Further, the main body CPU 27 deletes the deleted image data in which the failure avoidance setting is stored from the deletion history file, and ends the control (step S106).

  FIG. 8 is a flowchart showing a control procedure of the main body CPU 27 regarding calculation of the failure avoidance setting. The illustrated control procedure is executed in step S103 of the control procedure shown in FIG.

  First, the failure avoidance setting calculation module 55 sequentially reads shooting setting information among the deleted image data written in the deletion history file. In step S202, the failure avoidance setting calculation module 55 calculates a camera proper value as a reference from the shooting setting value in the read shooting setting information, and the camera proper value and the shooting setting actually applied at the time of shooting. Compare The camera proper value is a standard set value such as an exposure value when the exposure value is calculated according to a preset program diagram as a reference. That is, in step S202, the setting value that the camera system 1 sets as an appropriate value is compared with the setting value of the deleted image data.

  In step S203, the failure avoidance setting calculation module 55 lists the differences obtained by comparison as a frequency distribution. Steps S201 to S203 are repeated until there is no deleted image data in the deletion history of the flash ROM 29 (step S204: YES) (step S204: NO).

  When the deleted image data disappears from the deletion history (step S204: YES), the failure avoidance setting calculation module 55 exits the loop and calculates the correction value of the shooting setting value from the listed frequency distribution (steps S205 to S207). ). The correction value is calculated by statistical processing. Specifically, in step S205, the failure avoidance setting calculation module 55 calculates a section [a, b] having a less frequent value as the deletion history. The interval [a, b] having a low frequency value is defined as an interval between two maximum values a and b. In step S <b> 206, the failure avoidance setting calculation module 55 calculates the value difference c having the smallest deletion history, that is, the least frequent value in the section [a, b]. Then, the value c is set as a correction value in the section [a, b].

  For example, when a specific photometry mode is used as a reference, it is possible to list how many steps the exposure value of the deleted image data has as a frequency distribution. For example, in a section set every 1/3 stage, if there are local maximum values at +1/3 stage and -1 stage, a correction value of, for example, -1/3 stage having the smallest deletion history is set in this section. Is done. The set exposure value is used as an aperture value adjustment value when the shutter speed is fixed, and is applied as a shutter speed adjustment value when the aperture value is fixed.

  The control procedure as described above can be applied not only to the exposure value but also to various shooting settings. For example, contrast strength, saturation strength, before and after the focus point, zooming size, and the like may be handled as one of the shooting setting values. As described above, the failure avoidance setting calculation module 55 generates a correction value for the shooting setting value in the camera system 1 based on the shooting environment information extracted from the deleted image data.

  Note that the failure avoidance setting calculation module 55 may also acquire information from the image file of the captured image that has not been deleted. In other words, taking into account the number of images that were not deleted, replacing the frequency with the number of deleted image data relative to the number of shots, calculates a more accurate failure avoidance setting that reflects the intention of the user who deleted the shot image it can.

  Further, the failure avoidance setting may be acquired from another camera system 1 or an electronic device through the IP communication unit 31 when the operating time of the camera system 1 or the number of shots and the number of deleted images is small. However, since the user-specific tendency is difficult to be reflected, the failure avoidance setting generated by the camera system 1 is emphasized and the failure avoidance setting introduced from the outside is referred to according to the origin of the failure avoidance setting. The failure avoidance setting may be weighted.

  FIG. 9 is a flowchart showing a control procedure of the main body CPU 27 when shooting is performed using the failure avoidance setting. Shooting is executed in the camera system 1 when the user depresses the release switch 32.

  When shooting is started in the camera system 1, the main body CPU 27 acquires shooting environment information related to the shooting environment (step S301). Next, the main body CPU 27 reads from the failure avoidance setting file stored in the flash ROM 29 the failure avoidance setting corresponding to the shooting environment information common to the acquired shooting environment information (step S302).

  The read failure avoidance setting is set in the camera system 1 as a shooting setting value in this shooting (step S303), and the camera system 1 performs shooting by exposing the image sensor 9 under the shooting setting (step S303). S304). As described above, the main body CPU 27 of the camera system 1 performs shooting using the failure avoidance setting generated by the failure avoidance setting calculation module 55 as the shooting setting value. A photographed image photographed by the camera system 1 is recorded on the secondary recording medium 34 as an image file 50 in which photographing environment information is recorded together with photographing setting information (step S305). Thus, the control procedure of the main body CPU 27 for photographing is completed.

  As described above, since the camera system 1 performs shooting by applying the failure avoidance setting corresponding to the shooting environment information, there is a high possibility that the shooting setting value calculated by the camera system 1 is the user's favorite setting value. Takes less images to delete. In addition, failure avoidance settings are used according to the shooting environment information, so in various shooting environment situations, for example, shooting in the summer sea where you want to avoid overexposure, and shooting in the snowy mountains in winter where you can allow some overexposure. Appropriate failure avoidance settings can be applied.

  The camera system 1 may be provided with a setting for prohibiting reading of the failure avoidance setting when the user does not desire. Further, when the operation mode of the camera system 1 is set to manual shooting or the like, reading of the failure avoidance setting may be automatically refrained.

  FIG. 10 is a flowchart showing a control procedure of the main body CPU 27 when acquiring shooting environment information in shooting by the camera system 1. That is, the specific process of step S301 in FIG. 9 is shown. When acquiring the shooting environment information, the main body CPU 27 acquires date / time information regarding the shooting date / time from the calendar unit 54 (step S401). The date information can be calibrated with high accuracy by referring to the GPS signal received by the GPS module 16.

  Further, the main body CPU 27 acquires position information including latitude information, longitude information, and altitude from the GPS module 16 (step S402). At this time, highly accurate time information may also be acquired from the GPS module 16. Furthermore, the main body CPU 27 acquires weather information through the IP communication unit 31 (step S403). Furthermore, the main body CPU 27 also acquires map information (step S404) through the IP communication unit 31.

  As described above, in the camera system 1, the main body CPU 27 has environmental elements such as date and time information, position information, weather information, and map information, and acquires environmental information. Further, the main body CPU 27 comprehensively considers these pieces of information to generate shooting environment information (step S406). For example, by acquiring the date / time information and the position information together, it is possible to determine whether the shooting environment is classified into morning, daytime, evening, or nighttime. Moreover, since the light beam state is special in the sunrise and sunset time zones, it may be classified as an independent shooting environment. As described above, the main body CPU 27 generates shooting environment information associated with the case where the failure avoidance setting is stored from the collected environment information.

  Further, by determining together with the weather information, it can be determined whether the color temperature of the object scene is cloudy or clear. Further, by combining the map information, it is possible to determine and classify whether the shooting position is in some facility or outdoors. Furthermore, it can be determined whether or not the environment is a specific environment such as a sea or a mountain. Another sensor may be provided in the camera system 1 to collect more shooting environment information. In this way, if the number of environment information items to be collected is increased, it is possible to subdivide the classification of shooting environment information defined in a matrix form in the failure avoidance setting file, and to deal with more specific environments with high accuracy. .

  When the bracketing mode is set in the camera system 1, the main body CPU 27 may change the shooting setting value in the range [a, b] around the correction value c of the failure avoidance setting. For example, if the shooting setting value to be bracketed is an exposure value, bracketing shooting is performed with a shooting setting value in which the exposure value is shifted by 1/3 step in the range [a, b] around the correction value c. Execute.

  In addition, the main body CPU 27 uses a plurality of items corresponding to the adjacent items of the shooting environment information for classifying the failure avoidance setting in the failure avoidance setting file corresponding to the current shooting environment information as shooting setting values to be applied to the bracketing. Failure avoidance settings may be applied. Referring to FIG. 7 again, the environment setting information regarding the time may be fixed, and bracketing may be executed using adjacent failure avoidance settings belonging to spring, summer, autumn and winter. Thereby, for example, it is possible to execute bracketing shooting effective when the influence of shooting setting information according to the season is small indoors.

  Thus, the failure avoidance setting is stored in the failure avoidance setting file in association with the shooting environment information. Therefore, when the shooting environment changes, the failure avoidance setting according to the changed shooting environment is applied. Therefore, it is possible to reduce the correction of the shooting setting value by the user and to reduce the image files to be deleted after shooting.

  The camera system 1 may have a scene mode as a shooting mode. The scene mode is a shooting mode in which a combination of shooting setting conditions selected according to shooting environment conditions such as landscape, portrait, sunset, night view, and moving body shooting can be mounted in advance on the camera system 1 and selected. . For this reason, some of the combinations of shooting environment settings in the failure avoidance setting file may coincide with the combinations of shooting environments assumed in the specific scene mode.

  Therefore, such a failure avoidance setting may be reflected not in the shooting setting value but in the initial value of the scene mode. As described above, the failure avoidance setting calculation module 55 may change the shooting condition set in any of a plurality of shooting modes prepared corresponding to the shooting scene, based on the generated correction value.

  The failure avoidance setting calculation module 55 calculates a correction value when the interval between the shooting time when the shot image is shot and the deletion time when the shot image is deleted is within a predetermined threshold time. It is good to do. As a result, when the capacity of the secondary recording medium 34 is insufficient, the deletion of an image, such as when an old image is no longer necessary, and the intentional deletion of a shot image that does not conform to the user's shooting intention are distinguished. Thus, the failure avoidance setting calculation module 55 can calculate an effective correction value.

  Further, in the above-described processing, the description has been made on the assumption that information of a plurality of deletion image data is accumulated in the deletion history, but the plurality of deletion image data is image data for which deletion designation has been executed continuously. May be the target image data. As a result, the failure avoidance setting calculation module 55 can calculate a correction value that more strongly reflects the specific cause of deletion of the captured image.

  FIG. 11 is a flowchart showing a control procedure that can be executed by the main body CPU 27 in place of the control procedure shown in FIG. That is, when the photographed image to be deleted is designated by the user's operation using the cross button 36, the decision button 37, etc., the main body CPU 27 starts the control procedure shown in FIG.

  First, the main body CPU 27 reads the deleted image data including the shooting setting information and the shooting environment information when the shot image is shot from the tag data 51 of the shot image file 50 of which the deletion is specified (step S501). . Next, the main body CPU 27 extracts shooting environment information and shooting setting information from the read deleted image data (step S502).

  Next, the main body CPU 27 classifies the shooting setting information on the basis of the shooting environment information for each read deleted image data (step S503). Further, the main body CPU 27 stores the shooting setting information classified by the shooting environment information in the deletion history table stored in the flash ROM 29 (step S504). In this way, the main body CPU 27 ends the control procedure after deleting the photographed image. Note that the failure avoidance setting is not calculated in the above series of procedures.

  FIG. 12 is a diagram schematically showing the data structure of the above-described deletion history table. As shown in the drawing, in the deletion history table, shooting setting information of deleted shot images is classified according to corresponding shooting environment information. As already described, the shooting environment information has many items such as shooting date / time, shooting location, shooting direction, weather information, person, event information, and the like. Therefore, the shooting setting information is arranged in a matrix according to a plurality of shooting environment information.

  FIG. 13 is a flowchart showing a control procedure executed by the main body CPU 27, which is a photographing operation by the camera system 1 using the deletion history table. The shooting operation is started when the user depresses the release switch 32.

  When the shooting operation is started in the camera system 1, the main body CPU 27 acquires shooting environment information related to the shooting environment (step S601). The acquisition of the shooting environment information can be performed by the procedure already described with reference to FIG.

  Next, the main body CPU 27 reads shooting setting information corresponding to shooting environment information common to the acquired shooting environment information from the deletion history table stored in the flash ROM 29 (step S602). Subsequently, the main body CPU 27 causes the failure avoidance setting calculation module 55 to calculate failure avoidance settings from the read shooting setting information (step S603). The calculation of the failure avoidance setting can be executed by the procedure already described with reference to FIG.

  Subsequently, after applying the calculated failure avoidance setting to the camera system 1 (step S504), the main body CPU 27 exposes the image sensor 9 (step S605). Further, the main body CPU 27 generates an image file 50 in which shooting environment information is added to the shot image, and records it in the secondary recording medium 34 (step S606). Thus, the control procedure of the main body CPU 27 for photographing is completed.

  As described above, the shooting avoidance setting of the image deleted in the past is classified and held by the shooting environment information, and the failure avoidance setting is calculated at the stage of shooting, so that the failure avoidance setting can always be calculated by the latest calculation method. . Further, as the deletion image data is accumulated in the deletion history table, the accuracy of the calculated failure avoidance setting is improved.

  The series of embodiments has been described by taking the camera system 1 which is a lens interchangeable single lens reflex camera as an example. However, the above control can be applied not only to compact digital cameras and mirrorless single-lens cameras, but also to mobile phones. The failure avoidance setting also works effectively for still images and moving images of the video camera.

  FIG. 14 is a diagram schematically illustrating a personal computer 60 that executes an imaging condition generation program. The personal computer 60 is connected to the camera system 1 via a cable 61.

  The personal computer 60 has a display 62, a main body 63 and a keyboard 64. The main body 63 is loaded with a rear monitor control unit that performs predetermined image processing and displays an image on the display 62, a recording medium that stores captured image data through communication with the camera system 1, and a program to be executed. An optical drive 65 or the like used in the case is provided. Further, the main body 63 includes a processor that executes the loaded program.

  The personal computer 60 as described above operates as an image processing apparatus that executes the control procedure shown in FIG. 13 by reading a program. Further, the personal computer 60 can receive photographed image data from the camera system 1 via the cable 61 and can process it.

  Therefore, the user can delete the captured image, calculate the failure avoidance setting, and the like using the larger display 62 and keyboard 64. Further, the deletion history and failure avoidance setting stored in the camera system 1 can be stored in the personal computer 60, or the deletion history and worry avoidance setting stored in the personal computer can be transferred to the camera system 1. As a result, it is possible to accumulate a larger deletion history and to perform advanced calculation of failure avoidance settings.

  The data transfer between the camera system 1 and the personal computer 60 may be via a cable 61 as shown in the figure, or may be wireless communication. Alternatively, the photographic image data and the setting information may be delivered by delivering the secondary recording medium 34 in which the photographic image data is stored.
